React Job Details

The Institute

The Centro Nacional de Análisis Genómico (CNAG-CRG) is one of the largest Genome Sequencing Centres in Europe.

With the increasing demand in genomic tests on rare diseases, cancer and other diseases, genomic data management, analysis and interpretation is a real bottleneck in the healthcare systems. The Bioinformatics Unit at CNAG-CRG designs and develops innovative platforms and solutions to analyse large amounts of genomics and clinical data, with the ultimately goal of improving the implementation of data-driven and high-quality personalised medicine in the Healthcare System. Resources developed by the Unit are currently used by hundreds of clinical researchers in Europe and are part of major International genomic initiatives such as the Global Alliance for Genomics and Health (GA4GH), the European Infrastructure for life-science information (ELIXIR) and the 1+ Million Genomes Initiative (1+MG). The Unit includes bioinformaticians, engineers, software developers and biologists highly experienced on genomic data management, analysis and interpretation.

It is integrated with the Centre for Genomic Regulation (CRG), an international biomedical research institute of excellence, based in Barcelona, Spain, with more than 400 scientists from 44 countries. The CRG is composed by an interdisciplinary, motivated and creative scientific team which is supported both by a flexible and efficient administration and by high-end and innovative technologies.

In April 2021, the Centre for Genomic Regulation (CRG) received the renewal of the 'HR Excellence in Research' logo from the European Commission. This is a recognition of the Institute's commitment to developing an HR Strategy for Researchers, designed to bring the practices and procedures in line with the principles of the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers (Charter and Code).
